Claims priority, application Great Britain April 9, 1949 13 Claims. (Cl. 24235.5)

This invention is a continuation-in-part of our earlier application for United States Patent Serial No. 99,483, dated June 16, 1949, now abandoned, and relates to yarn winding machines of the kind in which the yarn is wound onto a core extending the full length of the package, whether it is a pirn, cop, spool or other package.

Such yarn winding machines comprise essentially a winding head having centres adapted to receive and hold an empty core on which the yarn is to be wound and which has the necessary yarn guide and traverse mechanism. Hitherto, automatic winding machines, whether singleor multi-spindle winders as they are termed, have merely brought the empty core, resting on a cradle,

. approximately into line with the centres of the winding station leaving the centres to do the final locating and gripping of the core. Moreover, after winding, the full package when released from the centres is quite free and allowed to fall to make room for the new core.

The present invention is based upon an appreciation that many of the stoppages with such machines is due to the freedom of the empty core and wound package respectively before and after winding, particularly where small or fragile cores are used.

One object of the present invention is an automatic winding machine in which, during the operation of removing a full package and inserting a new core, positive control of such package and of the yarn leading thereto is maintained until the interchange has been effected as compared with the previously known practice of merely releasing the full package from the winding station and allowing it to fall away relatively uncontrolled and without positively maintaining tension in the yarn. A further object is to enable this to be effected where winding occurs between centres one of which is axially movable to release the core and in which the full core also has to be moved axially for a less distance to release it from the other centre.

Still further objects of the invention are to be found in the features embodied in the appended claims for the positive control of the various elements and parts of the machine during the repeated cycle of winding operations.

As shown in the drawings the machine comprises a winding head A having a spindle bearing bracket B for the Winding spindle 10 shown dotted and which is coupled in known manner to the driving gearing (not shown) in the winding head. The winding spindle has a head 10 and a flange 111 Below and ofiset from the winding spindle is a rod 11 parallel with the axis of the spindle and fixed in the winding head. Slidably and rotatably mounted on such rod 11 is a sleeve 12 (see particularly Figures 3 and 4), at one end of which is an arm 13 having a head 13' on which are a pair of clamps each holding a U-shaped spring wire 15, the ends of each of which are turned into hold a roller 16. The clamps can be released for adjusting the position and tension of the gripping rollers. The clamps consist of the plates 14 secured by screws 14' (see Figure 5), which clamps hold the wires in grooves in the head so that the wires may be removed for the purpose of changing them for others of different size. The arm 13 is also adjustably secured on the end of the sleeve 12 so that the position of the rollers 16 relative to the quill 17 may be adjusted both radially and axially of the sleeve. At the other end of the sleeve is a toothed pinion 18 having a flange 18' a each side of larger diameter than the teeth.

Immediately below the rod 11 is a further rod 19 which is both slidableand rotatable and is carried at one end by a bracket 20 (see Fig. 4) attached to the winding head. The tail or tip end bracket 21 of the winding machine is carried by the rod 11 and a further stiff rod 22 located above the rod 11. The tail stock 23 which carries the tip end 23' is slidably mounted on these two rods 11 and 22 and is adapted to be moved positively backwards or forwards to advance or retract the tail stock of the tip end relative to the quill, such movement being eflfected from the automaton by a push rod 24 of flat cross section,

connected at 23 to the tail stock 23. Secured to the shaft 19 is a toothed quadrant 25 the toothed edge of which is located between the flanges 18 and is in mesh with the pinion 18. On the end of the shaft 19 adjacent to the headstock is fixed an arm 26 carrying a bowl 27 (see Fig. 4) which is engaged between cam edges 28, one only of which is shown, and which cam is driven by the automaton, such cam providing oscillatory movement in both directions of the shaft 19 and through the quadrant 25 and pinion 18 amplified oscillatory movement of the sleeve 12. Near the other end of the shaft 19 are fixed a pair of collars 29 spaced slightly apart and adapted to be engaged by a peg 30 on a lever 31 (see Fig. l) which is pivoted by one end to a bracket 32 attached to theend bracket 21. The other end of the lever 31 is forked and is engaged with a stud 33 (see Fig. 4) on the lower part of the tail stock 23.

Referring to Figs. 2, 3 and 5, it will be seen that the arm 13 has an ejector 34 of T shape, the tail of which is forked, the ends of the fork being bent round to clip over a pivot pin 35 about which the ejector is free to pivot. In the head 13' of the arm is an adjustable screw stop 36 the end of which forms a stop to position the ejector so that the head of the ejector 34 and the two rollers 16 provide triangulated holding points for the quill 17. On the rod 19 are fixed a pair of blocks 37, which are in register with the arm 13, so that as described later such arm can move between them and the ejector can be engaged with the ends of the blocks for ejection. of the quill.

Beside the rod 22 is a flat section bar 22' on which is slidably mounted a slide 38 to which is attached a collector fork 39. The slide 38 which rests on and is steadied by the rod 22 is adapted to be moved along the bar 22' by a link 42 connected to the automaton.

In operation, assume a quill is in the winding station and winding has just been stopped by any suitable measuring mechanism which at the same time starts the automaton, such mechanism being well known in automatic winders. The cam faces 28 commence to rotate and turn the shaft 19 which through the quadrant 25 and pinion 18 causes the arm 13 to rise pushing the rollers 16 over the quill 17 and so that the head of the ejector 34 rests against theu'rider sideof the quill (see Fig. 5 giving a triangulated contact withthe quill while the latter is still between the centres of the winding head. While the arm 13 is held in this position, the tailstock 23 is pushed back by the automaton through the push rod 24 which movement also,"throughthe "stud 33,'lever '31, peg 30 and collars29, pulls back the rod 19 through about half the distance of the'rr ovefment of-th'e tailstock 23. The rod 19 through the; quadrant 'ZSan'dfl'an'g'es 18 moves the sleeve 12 with its-arm 13 along the rod 11 through suchhalf distance. Thustlie tip end 23 is withdrawn from the quill 17 and thefquill'is 'withdrawnfrom the spindleihead 10', the quill beingfstillheldsubstantially in axial alignment with the centres of the {winding head.

v'emrit' (the spring'hotfbeing shown);the..housing Attached to the winding head A is a bracket 57 having a lug 5.8 from which .is .pivotallysuspended.an,.arm 59.having upper and lower forwardly directed projections 59 in each of which is fixed a rod 60. Adjustably mounted on the rods 60 are a complementary pair of channel members 61 which are adapted to be secured in position by clamping screws 62. This adjustment enables the channel members to be set for the required length of core 52 and also 'to determine'th'e relative axial disposition of the core which is presented to the winding head. .At the lower end ofeach channel member is a supporting spring 63 bent at its outer end't'o'form 'a cradle for one core which is located .therein by adjustable \anglepieces-6'4 secured to each arm. Fixed in the winding head A is a stud 65 on which is rotat'a'bly mounted 'arsleeve .65 carrying arms 66 and 67. The arm 67 carries a stud 68 engaged in a slot 69 in the l'owerend of the arm 59. The arm 66 is attached to a link 70 adapted to be operated by the automaton and the uppcr:end of which. arm 66 isadapted to engage and operate thetrigger 71 of a thread-severing device consisting of a guide plate 71" and scissors .type cutters 71 On aframe rod :72 carryingthe winding head Ais a bracket 73 carrying-a rod 7.40m whichare adjustably fixed a pair of arms7 5.

v lnvope'rationfithe cores '52 are stacked .loosely -in the channelmembers 61 of. the magazine, 'thelowermost core being supported on the arms75. One core.52';is also held in the cradle having been moved into thatiposition by engaging the f'front-of -:the ;arms 75 as the magazine mnvedba'ekinto the:.p'osition shown in Figure 1. When the 'link'70T is pushed by the automaton'the magazine is swungfforward until the corehel'd in the cradle is axially inline with'the winding centres and with the ends just clear of'thejpart's51and 23' shown'inFigure'6. When thetip end 23"is movedtowards'the spindle head I0"'as previouslydesc'ribed, 'it,.e'nters one end of the core and then slides it in'the cradle of 'the springs '63 until the core passes overthe end'j51 of the spindlc'head and until the gripping ofthe thread and of the'core at the winding centres has been effected. The automaton'then operates toswingback the magazine. The'lowerrnost core 52 in the magazine has fallen to the end of :thechannels as soon asit'le'aves'the support of the arms 75 .so that on'the return 'ofrthemagazine suchlowermost core engages the frontofjsuchiarms'andiszpushed bysuch arms into the cradle'of the springs 'while the upper-en'ds of the 'arms support the lowermost of the remaining cores. The springs .63 of course yield as the magazine is moved back toreleasethe core which has been'grippe'd in the winding-centres. The return movement of the arm 66 also operates the trigger 71- of the "thread'severing'device for the-yarn. It is'to be understood'thatthe'collectorfork 39-has beenfm'oved towardsthespindle 10 and located the yarnbehindthe "head l'tl' and in the severing device 71-(as -'s'ho'wn*in Fig. 10) beforethemagazine is moved bringing the empty core into position and that the magazi'neis returned to' the position shown -in Fig. l or at least as flgr as is necessary *before thecollector -'fo'rk l is i moved During the win'dingthe yarn is "guided-by a yarn guide 76 which is adapted to be"-rec-iprocatediii-known manner by mechanism is not-shown.

In the present'constructionhoweverthe yarn guide has *tobe raised for the passage-of the collector fork 39-and this is effected by the following mechanism. 5 Connected to the arm 79 -'is--a-'depending'curved'link"82' having a long slot "82 engaged'with apin 83 'carried by an arm 84 fastened to the sleeve 12 previously described. The quadrant "80' has aprojectio'n 8 0' whichis normally just clear of contact with a rod 85 'which is =pivotedat:its inner end.(-not-' shown) a'rid supportedattits other endin a' .s1otted lug 86 on-the tip :en'd bracket' 23.

lny operation, theUyarn guide-76 is free to rise as the quillvbuilds up andby its-- frictional .location ensures the.

building of a cylindrical quill, the link 82 sliding down over the pin 83. When the sleeve 12 is rotated to bring the grippers 16 on to the quill, the pin 83 engages the lower end of the slot 82' and causes the guide plate 77 to be raised where it is frictionally held in a clear position above the quill though the sleeve 12 and arm 84 turn back as the grippers are lowered with the quill. Thereafter, the collector fork moves to the left of Fig. 1 and its stud 38' merely pushes back the trigger without moving the rod 85. On the return movement of the collector fork, the stud 38' engages the cam face of the trigger 87 swinging the rod 85 outwards to engage the projection 80 on the quadrant 80 so that the quadrant is moved away from the friction block 79 allowing the plate 77 to fall until the yarn guide 76 engages the new core when winding can recommence. The stud 38' passes the trigger 87 to allow the friction mechanism to resume its normal position.

It is desirable for well known reasons that the length of yarn on the packages shall be as near constant as possible. Yarn winding machines are well known which embody a yarn length measuring device. Some of such devices operate by means of a measuring wheel around which the yarn is passed and which is rotated by the yarn and through reduction gearing which actuates the knock off mechanism, while others operate according to a predetermined number of turns of the winding head through gearing to actuate the knock-off mechanism. With a fully automatic yarn winding machine any measuring device must embody resetting so that the device comes into operation as the winding of each successive quill or other package is started. The present invention includes an improved construction of yarn measuring device which enables the yarn to be measured either by actual length or by spindle revolutions and which automatically resets itself and is adjustable to any predetermined measurement.

As shown in Figs. 7 to 9 and 7A the winding head spindle passes through the winding head A and has a pair of fast and loose pulleys, a driving belt 89 being shown in Fig. 8 in position on and covering the loose pulley, and passing over a pulley 90 on a main driving shaft 91. The fast pulley is not visible behind the winding head A. On the extreme end of the winding head spindle is an expandible pulley 92 of known construction coupled by a belt 93 to a pulley 94 geared in the winding head A to a cam shaft (not shown) operating the traverse of the yarn guide 76 (Fig. 1). Expandibility of the pulley 92 is provided for adjusting the proximity of consecutive turns of yarn, as is well known. Below the winding head, but not shown, is an automaton to actuate each cycle of change and consists as is also well known of a series of cams or other mechanisms on a shaft adapted to be rotated through a single revolution for each cycle of operations. Such automaton control is well known and in the example shown the rockingshaft 95 controls a belt fork (not shown) for the belt 89 and is connected by an arm 96 and link 97 to an arm 98 located on a pivot screw 99 fixed'in the end of shaft 100, the far end of the shaft being shown in Fig. 8. Behind the arm 98 and fixed to the shaft 100 is a lever 101 having at one end a stud 102 overlying the arm 98 and having at the other end a nose 103. The lever 101 is loaded by a spring 104 and its nose 103 is located in a guide slot 107 in the gate 107. On the pivot 99 and in front of the arm 98 is the starter lever 105 having a stud 106 adjacent to the stud 102 and also overlying the arm 98, the other end of the lever 105 being forked and having pivotally mounted therein a starting handle 105' located in a slot 107 in the gate 107. The starter lever is provided with a return spring 108.

On the side of the winding head A is a sleeve 109 journaled in the gate 107, such sleeve carrying a catch 110 complementary to the nose 103 aforesaid and against the rear face of the gate. At its other end the sleeve 109 carries a trigger 111 with adjustable stud 112 the upper end of the trigger being extended above the winding head A for manual actuation if desired. The sleeve 109 is urged by spring means (not shown) in a clockwise direction, i. e. holding the trigger 111 towards the winding head A and projecting the catch 110 into the path of the nose 103. Journaled in the shaft 109 is a rod 113 which carries operate on breakage of the yarn. The shaft 100 is adapted to be actuated through a link 116 (see Fig. 8) so that such link is pushed up by a cam 117 which is mounted on the end of the single-rotation automaton shaft 118, through a bell-crank lever'119, one end of which has a roller 120 to be engaged by the cam and the other end of which has a pin.121'.' Pivotally mounted on the shaft 118 by a pivot 122 is a clutch lever 123 carrying a clutch stud 124 the inner end of 'which is slidably located in the cam 117 and is adapted to be engaged with any one of a series of holes in a'gear wheel 126 which is freely journaled on the shaft 118 and continuously rotated by a pinion 127, the direction of rotation of the wheel 126 being shown by an arrow. The end of the lever 123 is wedge-shaped to a point at 123' as shown to engage with the pin 121 aforesaid and the lever moves about the pivot 122 as shown by its arrow. 5 a

In operation, the shaft 118 is caused to turn when the clutch lever 123 pivots so that its stud 124 enters one of the holes 125 in the continuously and slowly rotating wheel 126. As the shaft reaches the end of a single revolution into the position shown in Fig. 8, the wedgeshaped end of the lever 123 engages the pin 121 and thereby pivots the clutch lever to withdraw the stud 124. Before the wedge-shaped end of the lever 123 engages the pin 121 the cam 117 has raised the roller 120 rocking the lever 119 to bring the pin 121 into the path of the wedge-shaped end 123' of the lever. At the same time, through the link 116'the shaft 100 is rotated in a counterclockwise direction, as seen in Fig. 8 and thereby rocks the lever 101 raising its stud 102 clear of the arm 98. If the starting handle is down and engaged with the notch in the gate 107, the arm 98 may rise allowing the shaft 95 to turn counterclockwise in Fig. 7 under the action of a spring (not shown) to move the belt fork and bring the belt 89 on to the fast pulley thus starting the winding head. If the trigger 111 is manually pulled away from the winding head A it rocks the sleeve 109 drawing the end of the catch 110 away from holding engagement with the nose 103 allowing the spring 104 to turn the shaft 100 and depress the arm 98 by theaction of the stud 102 thereby moving the belt fork shaft 95 to move the belt on to the free pulley and thereby stopping the winding action. Such rotation of the shaft 100 is possible because the cam 117 has moved beyond the roller 120, so that the bell-crank 119 is now moved, withdrawing the pin 121, releasing the clutch lever 123 which under the action of a spring (not shown) presses the stud 124 against the face of the wheel 126 until it drops into one of the holes 125 when the automaton shaft 118 moves through one turn as previously described.

A measuring device is provided which normally stops the winding when the package has received a predetermined amount of yarn. In the example shown such amount of yarn can be determined either by the number of spindle revolutions or by yardage. The measuring device is located on the front of the winding head A and consists of a feed screw 128 adapted to be rotated by a ratchet wheel 129. In front of the feed screw is a rod 130 which is slidable and normally, urged to the right of Fig. 9 by a light spring 131 located between the casing and a collar 132 on the rod. The end of the rod has a head 133 adapted to engage the end of the 1 the feed screw.

screw 112 previously described. Slidably mounted on the rod 130 is a block 134 shaped at 134 with a half-nut to engage the screw 128 and beyond that with a fork 134 to engage an operating wire 135 attached to a rocking rod 136 by which the end of the block may be raised and lowered to disengage from and engage with In the casing is a setting device consisting of a screw 137 with operating head 137', carrying a stop block 138 which is positioned against rotation by engagement with the rod 130 and in turn is adapted to be engaged by the block 134. The block is re-set to engage such stop for, the beginning of each winding operation being moved to such position by a spring 139. On the block 134 is a pointer 140 adapted to register with apair of scales 141 (see Fig. 1) on the front of the casing the lower of which scales shows the numa trip lever 114 the end of which is adapted to engage shows yardage.
